ADCON has performed a wide range of engineering services to improve the conditions of municipal sites. A partial list of typical projects performed is as follows:

City of Philadelphia Municipal Services Building

    Cost of Construction:  $1.5 Million

ADCON performed an overall building assessment and provided the City of Philadelphia with a final survey report, which recommended corrective measures, including design drawings and specifications.  

The scope of work consisted of mechanical, electrical and plumbing engineering and design and specification services, including demolition of existing facilities, furnishing and installation of all materials and equipment as specified, to provide a new waterproof membrane as well as upgrading the structural, mechanical, electrical and plumbing facilities including a new transformer and power center. 









City of Philadelphia Simons Recreation Center

ADCON performed the mechanical, electrical, structural, and plumbing engineering and design services required to perform the renovations as the prime consultant.  The renovations included providing air conditioning to parts of the building that only had heat and ventilation.  We assessed the structural integrity of the building to ensure safe support of the new HVAC units, modified the electrical system for compliance with applicable codes and the requirements of agencies having jurisdiction over the building, and designed the necessary duct work to efficiently provide HVAC supply.








City of Philadelphia Fire Department Stations #59 and #64

ADCON performed the civil and structural engineering and design services required for the desired improvements to these stations.  We prepared engineering drawings and specifications for the project. ADCON also prepared preliminary cost estimates to support various options of work to be performed. ADCON was then retained to assist during the pre-bid phase, bid analysis and assistance as required during the construction phase.









City of Philadelphia Fire Department Station #11

ADCON performed the civil, structural, and geotechnical engineering and design services required for the renovation of the interior structural renovations of Station #11 as the prime consultant.  ADCON performed a geotechnical and structural investigation of the existing conditions to investigate the settlement problems that may be incurred while replacing the concrete floor, prepared a structural survey, and designed the concrete floor for the lower level and apparatus room.  ADCON prepared the engineering drawings and specifications, a project schedule, cost estimates, and construction administration related services.










Water Treatment and Pumping Facilities

ADCON has worked closely with the City of Philadelphia Water Department as the prime consultant on various types of projects.  Activities include geotechnical, civil, structural, mechanical, and electrical engineering and design services.  A partial list of typical projects performed can be found below.

  • City of Philadelphia Vare Street Pumping Station
The Vare Street Pumping Station is a facility that pumps storm water to a water treatment facility.  The renovations to this facility included the replacement of two existing pumps and associated piping.  Due to the nature of the facility, this design included temporary by-pass facilities to allow for the continuous operation of the pumping station while construction was taking place.  This project also included the replacement of electrical systems and the installation of new chain link fencing, new pavement, and a new gate.  ADCON performed the civil, structural, mechanical, and electrical engineering and design services for this project .










  • City of Philadelphia Linden Avenue Pumping Station
The Linden Avenue Pumping Station pumps sewage to a water treatment facility.  ADCON designed the replacement of the two existing pumps and associated piping.  ADCON also designed a new building on grade to house the emergency generator and new electrical controls for the pumping station, as well as the replacement or renovation of other items in the station.  Due to the nature of the facility, this design included temporary by-pass facilities to allow for the continuous operation of the pumping station while construction was taking place.  ADCON performed the civil, structural, mechanical, and electrical engineering and design services for this project.









  • Replacement of the Dehumidification System in Filter Building at Belmont Water Treatment Plant, Philadelphia, Pa

The dehumidification system is over 15 years old and primarily serves the filter building’s pipe gallery, which is located in the basement. The current dehumidification system is tailor- made/proprietary and is a mixture of parts from various companies. The dehumidification system was non-functioning.

Adcon performed a survey and inspected the existing conditions of Philadelphia Water Department’s (PWD’s) Belmont Water Treatment Plant. Adcon prepared the assessment and basis of design report. Adcon performed engineering design for the replacement of the dehumidification system and related engineering design (HVAC, mechanical, and electrical). The intent of the design was to reduce the presence moisture in the pipe gallery.

Adcon provided engineering design for the installation and operation of a new dehumidification system, including a new dehumidification unit that would maintain the pipe gallery space at, or below 40% relative humidity (RH) (+5% RH). The engineering design included but was not limited to the removal of the ductwork, insulation, structural support accessories, hot water piping, and high-pressure gas piping. The engineering design also included the installation of a new recirculation fan, exhaust fan, heating coil, gravity vent, fire and backdraft dampers, air monitoring stations, insulation, structural support accessories, water piping, high-pressure gas piping, valves, and miscellaneous items.

The electrical engineering design portion of the project involved disconnection and removal of the existing electrical components, including wiring from the existing dehumidification system. Also, Adcon performed the engineering design for the installation and connection of the new dehumidification system. The design also pertained to but was not limited to the wiring to the supply fan(s), exhaust fan(s), recirculation fan(s), sensors (including those in the pipe gallery), motors, and dampers.

Adcon also performed construction administration services for this project.








  • City of Philadelphia Northeast Water Pollution Treatment Plant
ADCON performed the electrical engineering and design services required for the renovation of the plant. The existing control system takes the 4-20 ma signal for the 48 inch venturi meter and automatically modulates the speed of the pumps.  The local meters provide a signal to the control system for display and recording of the readings.  The function and programming of these meters was not changed, but the location and type of meter was upgraded.  Nine motor-operated valves were replaced by manual valves, and four motor operated valves and their dp switches were being replaced in kind, eight flow meters were replaced, and a new discharge flow meter was added.  ADCON prepared the design drawings and specifications.
